ORE-SEPARATORa SPECIFICATION forming part of Letters Patent No. 245,155,dated August 2, 1881. Application filed October 15, 1880. (No model.)

To all whom it may concern:

Be it known that 1, LEVI M. GOCHNAUER, of Lancaster, in the county ofLancaster, and in the Stateof Pennsylvania, have invented certain newand useful Improvements in Ore- Separators; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification. r

This invention relates to certain improvements in that class ofseparators for iron and other similar ores in which a series or gang ofshovels pivoted to a series of reciprocating bars are employed inconnection with an inclined sluice box or trough, through which acurrent of water is passed to separate the lighter from the heavierparticles of the ores 5 and it has for its objects to provide animproved means for hanging the shovels to their respective reciprocatingbars, whereby they will be operated in line with said bars and preventedfrom twisting the same, and ,also to provide for limiting'the movementof the shovels upon the backward reciprocation of the bars, as morefully hereinafter specified. These objects I attain by the apparatusillustrated in the accompanying drawings, in which- Figure 1 representsa longitudinal sectional view of my improved apparatus, and Fig. 2represents a perspective view of one of the shovels and itssupporting-hanger.

The letter A indicates an ordinary inclined sluice box or trough,supported in the frame B, and provided with a metal-lined bottom, 0,curved upwardly atits lower end, as indicated by the letter D. The saidframe is provided with a series of transverse shafts, E ,to which arepivoted a series of swinging arms, F, which are bifurcated at theirlower ends and carry the reciprocating longitudinal bars G, which whichare curved upward at their lower ends correspondingly to the curve atthe lower end of the sluice box or trough.

The letter H indicates the shovels, and I the standards or hangers towhich the shovels are pivoted, thesaid hangersbeing provided withupright lugs t at each side, which enlbrace the bars G, and are securedto the same by screws K. The lower part of the hangers is curved at therear and recessed at the forward portion, as indicated by the letter L,for the reception of the upper ends of the shovels, which are pivotedtherein, the rear curved walls ofthe recesses serving as a stop to limitthe rearward movement of the shovels as they are carrying the oreforward.

The letter M indicated a transverse shaft carrying a series ofeccentrics, N, corresponding innumber to the reciprocating bars, thesaid eccentrics being provided with the ordinary straps and rods, thelatter of which are pivoted to the respective bars, as indicated by theletter 0. To one end of the shaftMis secured a driving-pulley, throughthe medium of which the apparatus is put in motion.

Theapparatus is provided wit-h ahopper, B,

through whichthe ore is introduced.

The operation of myin vention will be readily understood in connectionwith the above description.

' The ore is fed into the hopper and water. let into the sluice-box atthe upper end. The ap paratus is then putinto motion, the shovelsoperating to carry the ore up the inclined bottom LEVI M. GOOHNAUER.
